A compound bow, including a center handle portion, upper and lower limbs having inner ends connected to the center portion and free outer ends. Upper and lower draw pulleys are eccentrically mounted respectively on axles mounted on the free outer ends of the upper and lower limbs with a first draw cable having one end positioned adjacent the lower draw pulley and extending across the bow and with the other end of the first draw cable extending around the upper draw pulley. A free end of the first draw cable extends tangentially from the outer surface of the upper pulley. A second draw cable has one end positioned adjacent the upper draw pulley and extends across the bow and with the other end of the second draw cable extends around the lower draw pulley and having a free end extending tangentially from the outer surface of the lower pulley. A bowstring interconnects the free ends of the first and second draw cables. A coupling device couples one end of the first draw cable to the free outer end of the lower limb, and a second coupling device couples one end of the second draw cable to the free outer end of the upper limb, and the first and second coupling devices divide the load in the draw cables and couple the load to opposite sides of each draw pulley. Each coupling device is formed of an idler pulley and a short length of cable wrapped around the idler pulley.
